********************************************************************************************* (Sept. 2011) A Battery Design Fault Leads to a Recall by Medtronic A Class I recall by the FDA on Medtronic’s SynchroMed ll (an implantable pump which delivers drugs) was announced on September 12, 2011. A malfunction caused by a film formation on the pump’s battery caused the pump to stop therapy. Such problems were not noted until 45 to 78 months after the pumps had been implanted. Models 8637-20 and 8637-40 could be defective because of the batteries. Physicians have been alerted. Medtronic received FDA approval for a new battery design in July for the pumps. Shipment of new units has already begun.
